Fuucckk. How the hell did you get out the car & stop Hana from pulling the drivers nose out of their arse, if your knee was fucked!?!?
I know many will have said "You're lucky/Be thankful it's only your knee" & that part of you knows they mean well, but I also know how dark & deep the hole can get, in such a situation.
So: If there is anything any of us can do, to help you out: Please be sure to let somebody else know - 'cause I am useless at shit like that.
(If you need stupid/self-deprecating/silly - That I can do.) ;)
